Abstract

Procedimiento de grabación de CD-ROM Para evitar su copia. Realiza la grabación con láser de los ficheros de la aplicación mediante un proceso convencional de mastering. Se caracteriza porque en dicho proceso de mastering se graban al menos dos tramos T1, T2 de ficheros en los cuales no existe ningún fichero de la aplicación y entre los cuales debe existir al menos un fichero de la aplicación. Además se graban una pluralidad de ficheros de complemento muy parecidos a los de la aplicación de forma que la grabación total supera el tiempo total de grabación previsto en los discos vírgenes disponibles en el mercado. Seguidamente se efectúan unas marcas láser M1-M3 mediante sobreescritura en los ficheros dispuestos en tramos T1, T2, siendo estas marcas ilegibles para el lector de CD-ROM; todo ello de forma que aunque al realizar una copia se salten las marcas, es necesario eliminar ficheros para que quepan en el disco virgen standard.
